Abstract

The invention provides a power ammeter shell material and a preparation method thereof. and relates to the field of power materials. The power ammeter shell material is prepared from the following raw materials in parts by weight: polyvinyl chloride, polyethylene, methyl methacrylate, glass fibers, polycarbonate, polylactic acid, decabromodiphenyl ethane, polydimethylsiloxane, chitin, silicon nitride powder, silicon carbide powder, sodium succinate, talcum powder, barium sulfate, graphite powder, ceramic fibers, boron carbide, zircon powder, aluminum nitride powder, isoprene rubber, phenol-formaldehyde resin, a flame retardant, a plasticizer, a compatilizer, a thermal stabilizer, a light stabilizer and a curing agent. The preparation method comprises the following steps: (1) weighing the raw materials; (2) centrifuging, melting, feeding into a mold, sizing and cutting. By adopting the power ammeter shell material, the problems of an existing power ammeter shell material that properties including mechanical strength, thermal stability and flame retarding property still need to be further improved and strengthened are solved.

Description

technical field [0001] The invention belongs to the field of electric power materials, and in particular relates to an electric power meter casing material and a preparation method thereof. Background technique [0002] The housing of the meter is mainly used to protect the internal parts of the meter, which requires good mechanical properties, good thermal stability and flame retardancy. At present, flame-retardant ABS is mostly used as the housing material of electric meters in China. Although flame retardant ABS is cheap, its rigidity is not very good. Reinforced polycarbonate (PC) is mostly used abroad at present. With the development of my country's economy, a large number of reinforced PCs will be used as the housing material of electric meters in China. Polycarbonate is a colorless, transparent, amorphous thermoplastic material. Its chemical properties are resistance to weak acids, weak bases, neutral oils, ultraviolet light and strong bases. Its physical properties...
